A cosmetic product with excellent tactility and slip quality during skin application is provided. This cosmetic product includes microparticles and other cosmetic raw materials. The microparticles are formed from a biodegradable polyester resin containing 50 mol % or more of lactic acid units in relation to the resin component, with the content of D-lactic acid among the lactic acid units being 0.1 to 25 mol %. 70% or more in entire number of the microparticles satisfies the ratio of the large diameter to the small diameter as being equal to or less than 1.5. The density of the microparticles is 1.0 to 10.0 g/cm 3 , the average particle diameter is 0.01 to 1000 μm, and the 10% deformation strength during compression is 5 MPa or more. |
